Theoretical Investigation of the Amplitude Modulation of Supersonic Waves During Passage Through Turbulent Water Flow . Theoretische Untersuchung ueber die Amplitudenmodulation von Ultraschallwellen Beim Durchgang durch Turbulente Wasserstroemungen

摘要

The passage of sound through a turbulent stream and the expansion reaction with turbulence dispersion are described. The amplitude modulation of an ultrasonic wave passing through a turbulent water stream is discussed. It is shown that the beam with turbulence dispersion are described. The amplitude modulation of an ultrasonic wave passing through a turbulent water stream is discussed. It is shown that the beam axis of the sound is perpendicular to the beam axis of the free stream. Frequency spectrum analysis is used to determine the structure of the current in the free stream. It is shown that the expansion and the intervals existing in the stream directions can be determined.
